This invention relates to windows, and with regard to certain more specific features, to sash hanging construction for windows.

Among the several objects of the invention may be noted the provision of a window sash which is readily removable from its hinges when in an opened position but which is not removable therefrom when in a closed position; the provision of a window sash which is adapted to form a weather tight joint with a sill member of awindow frame and which permits of substantial vertical movement when in a closed position in said frame and which therefore cannot be jammed between the top and bottom of said frame; the provision of a window frame and sash of the class described, said sash being adapted to ride up on the sill of said frame when said sash assumes a closed position; and the provision of a hinge construction for hanging said sash, said constructions permitting of vertical and rotational movement of said sash but not permitting lateral movement thereof; and the provision of a window construction which is practical, easy to install and non-binding with respect to enlargement of the wooden portions thereof as occasioned by changes of humidity, or weather changes. Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly comprises the elements and combinations of elements, features of construction, and arrangements of parts which will be exemplified in the structure hereinafter described, and the scope of the application of which will be indicated in the following' claims.

In the accompanying drawings, in which are illustrated several of the various possible embodiments of the invention,

Fig. 7 is a vertical section of the hinge modification taken on line 7-7 of Fig. 6,

Similar reference characters indicate corresponding parts throughout the several views of the drawings.

Referring now more particularly to Fig. 1, at numeral 1 there is illustrated a window sash hung in a window frame on hinges 25. The window frame comprises a head jamb 3, a sill member 5, and side jambs 6 (see Fig. 2). It is noted that the head jamb 3 has reotangular grooves or rabbets 12 and 13 formed along the bottom edges thereof, the groove 13 being deeper than the groove 12. It is also noted that the side jamb 6 has a groove 9 formed along one edge thereof, and a second groove 11 formed along the other edge thereof. The recess formed by the grooves 9 and 12 forms a seat for a screen or the like to be positioned in the window frame, the base of the screen resting on the sill member 5. The recess formed by the grooves 11 and 13 provides a seat for the window sash 1. Another groove or rabbet is formed in the lower portion of the side jamb 6 and is adapted to receive the sill member 5 in a loose fit. In securing the sill member 5 between the side ambs 6 a wedge or the like is driven between the sill 5 and the under edge of the groove 10 to hold the sill while it is being permanently fastened, as by nailing to the side jamb 6. After the sill is thus permanently fastened to the side jamb 6 the wedge is withdrawn leaving thefree area between the sill 5 and the lower portion of the groove 10 as shown at numeral 14. A strip 7 seated in the outer surface of the side jamb 6, is adapted to interlock the side jamb 6 with the masonry or the like in which the same is set. It is to be understood that the window frame may be made from metal or any other suitable material, and is not limited to the specific constructions shown in Figs. 1, 2 and 5.

The sill 5 is formed with an enlarged front portion 115. The portion 15 at one side is shaped with a reentrant curvature 17, and

formed by the grooves .13 and 11 and the sash one is such that when the sash 1 is positionedthereimas when in a closed position, the outer faces of the sash are flush with the side and head jambs. Moreover, there is a substantial space left between the ends of the side pieces 21 of'the-sash'l and the edges of the side jamb "6 asshownv at numeral 47. Thebottom piece of'the sash 1 as'shown at numeral 49 is made to conform to the general shape of the corresponding part of the sill -member'5 as shown in numeral15, and when the sash 1 is inra closed position, the piece 120 rests on the sill member 5. The bottompiece '20 is bevelled on its rear edge, .as illustrated atnumeral 75.

Referring nowmore particularly to Figs. :3 and 4, there is shown at numeral '25 one Ofithe hinges for'sndn-ginglysupporting the window sash 1. Each hinge comprises a bearing plate 51; and a pintle plate 53. The 5 hearing platehas an open bearing '55 formed therewithbybending the :plate 51 at the bot- :tom of the bearing 55 to form the guide walls 57:and 59. Theouter guide 59 ispositioned in a plane removed from but parallel to the .40 :p'laneof the inner guide 57.

The pintle portion53 carries a pintle 61 which maybe either loosely or rigidly held by bearings 63, :formedby extensions of the plate 53. The pintle -61 is provided with heads 65 to prevent'itsbeing removed. The

width of the bearing55 is such that-it will just-pass between the bearingmembers '63 which holdthe pintle-61.

.Asis-seen in Fig. 4 the bearing 55 is adapted to freely receive the pintle or pin '61. The guiding-walls '57 and 59 guide and maintain 'the -pin-61 in the bearing even fthough the'pin 6.1;ismoved a substantial distance from thebottom :thereof. It is point- .ed-voutfhowever, that theipintle has only rotational and vertical movement in'the bearing; other movements being prevented by the fit of the members. The bearing plate 51 is made up from sheet metal which is substantially thicker than the metal forming the pintle plate Thus, not only is a stronger1bearing'55 presented, but also when the sash 1 is closed,-the inner surfaces of the bearing plate 51 and the pintle plate'53 are positioned inthe same-plane. The'relatively greater thickness of the bearing plate 51 also serves to prevent jambing of the sash 1 in the frame, such as might occur were it the same thickness as the pintle plate 53.

To hang the window sash in the position illustrated in Fig. 1 the plates 51 and 53 are first, separately fastened to the head jamb 3and sash frame 19, respectivel this being done by means of screws 67. It is to be understood that any suitable number of hinges may be used for each window sash. The sash 1,is then held in a plane which is at an angle to that of the window frame, and the pintles-61 of the hinges 25 are slid into the open end of the bearings 55 and to the bottom thereof. WVith the pins 61 seated in the bearings 55 the sash is'swung down. As'the sash is so moved, the top inner edge of the window sash frame 19 engages the inner face of the groove '13. As'the 'sash1 isfinally received in the recesses formed by *the'rabbets 13and 11, thelower portions i9 ofthe asa'sh pieceJ2O, particularly at the bevel 75, engages the llIl- 'clined 'curvedsurface 17 ofthe sill 5 and; rides thereby preventing any binding whichmight occur between the sash andlthe frame. The upper part of the window frame although not supported b'y the hinges 5 is'held against the head jamb 3 by the engagement of the pintles Gland the side walls 59 of'the'bearings Lateral movement ofthe sash "is also prevented by the hinges 25.

It is understood that thegrooves 11 and 13 of the window frame or casing maybe eliminated if desired as in a window construction not exposed to the weather. Moreover, the incline as shown in Fig. 1 may be of .any suitable shape capable of enabling the sash to ride up on the sill thereby providing a weathertight joint between the bottom piece 20 of the sash 1 and the-sill 5.

In Fig. 5 there is illustrated a modification of the groove or rabbet '11, shown at numeral 73. In this modification, instead of being rectangularly shaped, the groove 11 has a stepped shape. The. sash piece hasiits juxtaposed edge out to correspond to the general shape of the groove as shown atnumeral 73. This type of rabbet joint provides a more weather proof joint between'the sash and the side jambs.

Referring now to Figs. '6 and 7 there is shown a modification of the hinge shown in Figs. 3 and .4. This modified hinge comprises a bearing plate 27 and pintle plate 29. The bearing plate 27 has an open bearing 35 extending downwardly as a U-shape and extending at least partially over the edge of the recess in the frame. The bearing 35 is formed by an extension of the plate 27 bent at the bottom of the bearing to form guides 31 and 33. The outer guide 33 of the bearing 35 is positioned in a plane removed from but parallel to the plane of the inner guide 31. The inner guide is spaced outwardly by means of the oiff'et 36. The offset 36 is the functional equivalent of the relatively thicker bearing plate of the Fig. l embodiment. To compensate for the offset 36, a similar oil'- set 38 is formed in the extensions of the plate 29. In this way the faces of the plates 27' and 29 are brought into the same plane, as the sash l is seated in the window frame.

A latch, as illustrated at numeral 71 may be employed to lock the window sash in a closed position.

The window frame may be adapted for mounting the sash inside of a room or outside.

In view of the above, it will be seen that the several objects of the invention are achieved and other advantageous results attained.

As many changes could be made in carrying out the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

I claim 1. In combination, a frame having a recess, at least one hinge adjacent the recess and having a pintle receiving portion, and a sash, a pintle supporting portion fastened to said sash, said pintle receiving portion being of thicker material than said pintle supporting portion, said receiving portion being open so as to permit application and removal of said pintle and to permit movement of the pintle therein laterally of its own center line, the difference in thickness of said pintle receiving portion and said pintle supporting portion functioning to prevent said sash from jamming in said frame.

2. In combination, a frame having a recess, at least one hinge mounted on the upper edge of said frame, said hinge having a pintle receiving portion extending over the up per edge of said recess, and a sash, a pintle fastened to the upper edge said sash, said receiving portion being open so as to permit application and removal of said pintle and to permit vertical movement of the pintle therein, said frame and said sash having engaging means on their respective lower edges adapted upon swinging of the sash into the frame, to cause the sash to rise in the frame, thereby to secure a weather-proof joint, the upper portion of said sash then being locked behlnd said receiving portion, said means comprising similarly curved inclined surfaces on the juxtaposed lower portions of said sash and frame.

3. In combination, a closure, and a frame having a recess adapted to receive the closure, said closure being hinged to said frame by at least one hinge, to swing about its upper edge, said hinge being adapted to permit substantial vertical movement of said closure, said frame and closure having engaging means substantially opposite the hinge adapted to cause movement of the closure substantially vertically upwardly in the plane of the frame when said closure is swung into said frame, thereby to secure a tight, weather-proof joint.

In testimony whereof, I have signed my name to this specification this nineteenth day of January, 1931.
